Skip if

Foam earplugs (disposable)

28–33

All-shift industrial noise, daily replacement

Hand hygiene during insertion is a concern

Reusable plugs (flanged)

25–30

Workers going in & out of noise all day

You need the absolute highest NRR

Banded plugs (semi-aural)

17–25

Quick on/off for intermittent noise

Sustained heavy noise — NRR is lower

Earmuffs (over-the-head)

22–31

Visible compliance, easy on/off, no insertion fiddling

Hot environments or safety-glasses users

Dual protection (plugs + muffs)

+5 over best

Anything above 100 dB exposure

You don't actually need it — workers won't wear it

 

Pick This If...

•        Your team is on the floor all shift in steady noise → foam plugs

•        Workers walk in and out of noisy zones all day → banded plugs or muffs

•        You need to see compliance from across the room → earmuffs

•        You're in food / beverage / pharma → corded, detectable plugs

•        Exposure is over 100 dB → dual protection, no exceptions

OSHA requires variety

You can't hand every worker the same yellow foam plug. The standard requires offering at least one earplug type and one earmuff type so workers can find something they'll actually wear.

The Real Decider

Comfort beats spec sheet. The best-rated product in the world protects nobody if it sits in a pocket. Stock more than one option and let workers pick what they'll actually keep in.
